Appucation September 30, 1952, Serial No. 312,340 3 Claims. (Cl. 16115)This invention relates to a door pull for sliding doors. An ob ect ofthe invention is to provide for slidable doors, a door pull having ahousing provided with a pair of laterally adjustable side plates, thusadapting a single size of door pull housing to be smoothly fitted to thenotched front edge portions of slidable doors varying considerably inthickness.

The door pull structure provided by this invention is constructed insuch a manner that it is convenient, when installing the device on adoor, to apply to a door between two rooms side plates which will matchwith the fixtures of each room, for example, a chrome plate on one sideand a brass plate on the opposite side.

The invention further relates to a new and advantageous assembly ofparts which can be easily installed upon a slidable door in a moreaccurate, rapid and satisfactory manner.

Other objects, advantages and features of invention will hereinafterappear.

Referring to the accompanying drawing, which illustrates a preferred,reduced to practice embodiment of the invention,

Fig. l is an extended, perspective view illustrating the application ofthe device to a slidable door, the latter being fragmentarily shownprovided with a notch in its outer end dimensioned to have the devicefitted thereinto. The pull arm of the device is shown slightly outswung.

Fig. 2 is a perspective view showing the device in its mounted positionin a fragmentarily shown door.

Fig. 3 is a perspective view of the frame portion of the door pull, perse.

Fig. 4 is a perspective view reproducing Fig. 2 except that the pull armis shown outswung and a screwdriver is fragmentarily shown applied tothe internal fastening screw in readiness to screw it into the notchedportion of the door.

Fig. 5 is a front perspective view showing the pull arm out swung to itsmost elevated position. In this view the adjustable side plates areshown in full lines positioned for application to a relatively narrowdoor and in dotted lines as they would appear when applied to a thickerdoor.

Fig. 6 is a vertical, longitudinal section, the plane of sectionextending along the midwidth part of the device.

Fig. 7 is a fragmentary, vertical section of the device, one of the sideplates being shown detached, but positioned adjacent to its mountedposition. The plane of section is indicated by line 77 on Fig. 6.

Referring in detail to the drawing, the embodiment of the device thereinshown comprises, as to main parts, a rectangular, open frame 10dimensioned to fit into the rectangular notch 11 in the slidable door12. except that the thickness of said frame is less than the thicknessof the notched portion of said door; a swingably mounted pull arm 15;and the twin, reversible side plates 16, which are attached to saidframe and door to conceal the parts contained within said notch 11.

Said frame 10 is of a skeletal character and comprises a rectangularlyU-shaped metal strip having arms 19, the basal or midlength run of the Uextending vertically and forming the inner portion of the mounted frame.At its front side said U-shaped strip carries, preferably integrally, achannel shaped structure which comprises the vertically extending sidestrips 21 and incomplete web portion 22, the open side of this channelshaped structure being directed outwardly. The aforesaid pull arm 15 isshown swingably mounted upon a cotter pm ice 26 which bridges the spacebetween the upper end portrons of said strips 21, said pull arm carryingat its free end a deflected fingerhold end portion 27. Said pull armswings vertically in the alcove 28 provided by the channel shapedstructure which has been described, this channel structure carrying stoplugs 29 to limit the inswing of said arm.

Said incomplete web 22 occupies only the midlength portion of saidaforesaid channel shaped structure so that a space is left above saidweb allowing the inner end portion 30 of the fully outswung pull arm toabut the upper end-of said web, and there is also a space below thelower endof said web which accommodates the outer end of the fingerhold27 of the pull arm, allowing said arm to fully inswing. Said arm portion30 is manually depressible partly to outswing the arm.

Integral with the midlength portion of the web 22 is a cup shaped member33 the mouth of which is directed forwardly. This cup is concentric withan integral part of a tubular member 35 which spans the space betweenthe bottom of the cup and the rear portion of the frame body 10. Thetube 35 is dimensioned to receive the shank of an interior fasteningscrew 36 while the head of said screw occupies the cup 33 to be engagedby a screwdriver 37 when the screw is inserted. This screw is located atthe midwidth of the frame 10.

Each of the aforesaid side strips 21 carries along its front edge anoutwardly directed flange 40, these flanges widening the horizontaldimension of the front portion of the device so that the space betweentheir outer edges is sutliciently wide to take care of the thickness ofthe notched portion of the narrowest door to which the device is to beapplied.

The housing structure afforded by the device is completed by theprovision of the aforesaid pair of structurally twin side plates 16 eachof which carries along its front edge an inwardly directed flange 47which overlies the adjacent front surface of the frame structure whichhas been described to a greater or less extent in accordance with thethickness of the notched part of the door to which the device isapplied. Each of said plates 16 has, throughout its central portion, aconventional fingerhold depression 49 usable to slide the partly opendoor farther out. A forward screw 50'co-operates with a rearward screw51 to attach each of said side plates. Said'screws 50 screw into thefront portion of the frame 10 and the screws 51 screw into the intactportion of the door rearwardly of its notch 11, the plates 16 havingthrough them suitable screw holes for these screws.

After a suitably dimensioned notch 11 has been cut into the door thepull is slipped into said notch, bringing the pull arm 15 flush with theouter surface of the notched part of the door as shown in Fig. 2. Thenthe front screws 50 will be ti htened adjusting the frame to center atthe same time. Next screw in the two wood screws 51. Lastly insert thewood screw 36.

Owing to the skeletal character of the frame 10 its side portions afforda clearance for the aforesaid fingerhold depressions 49 of the sideplates 16.

I claim:

1. structure of the kind described comprising a substantiallyrectangular frame fitting within a notch in the front edge portion of aslidable door with the front portion of said frame substantially flushwith the front edge surface of said door, there being an alcove in saidfront portion of said frame and a web portion at the back of the alcove,a pull arm swingably mounted in said alcove and normally held by gravityin a downswung position wherein it closes the front side of said alcove,a part of said arm contacting. said web portion to form a stop for themotion of said arm in one direction, said frame carrying a verticallyextending lateral flange along each side of said alcove, said flangesbeing sufliciently wide to afford between their outer edges a spaceequal to the thickness of the narrowest door to which the device is tobe applied, and a pair of side plates mounted in positions whereln they.conceal the sides of the aforesaid frame when the latter is within saidnotch, each of said side plates viewed in its applied position extendingabove and below said notch and each having an inwardly directed verticalflange along its front edge, each said plate flange overlying theaforesaid frame flange at its side of the doorto a greater or lessextent 'in accordance with the thickness of the notched part of the doorto which the device is applied, and a lug in said alcove contacted bysaid arm to form a stop for the motion of said arm in the directionopposite to the first mentioned direction.
